Application April 27, 1938, Serial No. 204,688 Renewed October 6. 1939 2Claims.

This invention appertains to new and useful improvements in toyaeroplanes and more particularly to a toy aeroplane which can beconveniently wound up and which in operation will simulate the flight ofa bird through the medium of flapping wings.

Another important object of the invention is to provide a toy aircraftof the character stated which will be of such construction that it canbe repaired easily in the event damage is done to the same in landing,or in other ways.

These and other objects of the invention will become apparent to thereader of the following specification.

15 In the drawings:

Figure 1 represents a top plan view.

Figure 2 is a side elevational view.

Figure 3 is a front View.

Figure 4 is a fragmentary perspective view of the frame.

Figure 5 is a fragmentary perspective View of the manner in which one ofthe wing ribs is connected to the main frame.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that the main frame consists of an elongated member 5 havingthe elongated cross plate 6 at its forward end. This cross plate 6 maybe of some very light wood as is the elongated member 5 and extendingfrom the ends of the plate 6 and rearwardly are the rearwardly taperedribs 1-! which can be of bamboo or some other highly flexible but lightmaterial.

At each end of the cross plate 6 is a pivotal connection such as isgenerally referred to by numeral 8 between the corresponding arcuatewing member 9 and the plate 6. Each of these pivotal members 8 consistsof a wire member which has one portion In disposed,parallel to thecorresponding end of the plate 6. One end portion of the wire member IDis bent downwardly as at I I and then outwardly to pass along the sideof the corresponding end portion of the rib 9, while the other endportion is bent downwardly and inclined forwardly as at I2 and thenupwardly to form the V-formation l3. The upper end of this V-formationis bent outwardly as at 54 and this end and the first-mentioned end ofthe wire member are secured by suitable wrappings l5 to the adjacent endof the rib 9.

The apex portion of the V-shaped formation l3 extends through theadjacent end of the pitman Hi.

It can now be seen, that a single sheet I! of 55 silk or some othersuitable material is spread over the top of the plane encompassing theplate 6, wing ribs 9 and central ribs I and suitably secured to thesemembers and to properly secure the portion iii of the pivoting member inplace a strip of adhesive plate or the like l8 can be employed in themanner suggested in Figures 4 and 5.

Numeral 59 represents the tail member which is suitably secured as at 20to the rear end of the elongated member 5.

The propelling means, supplementing what is shown in Figure 5, consistsof the inverted U- shaped bracket 2i through which the crankshaft 22extends, the crankshaft 22 extending forwardly of the elongated memberand having the hand crank 23 formed at its forward end.

The rear end of the crankshaft 22 has the hook formation 23 which ishooked over one end of the elongated elastic band 24. The other end ofthe elongated elastic band is disposed over the hook 125 which islocated at the rear end of the elongated member 5.

The crankshaft 22 is provided with the cranks 285 and 2? with which theinner ends of the pitmans 16 are connected.

It can now be seen, that by rotating the hand crank 23, the elastic band24 can be wound and thus tensioned so that when the hand crank 23 isreleased, the crankshaft 22 is caused to rotate rapidly with the resultthat the pitmans I6 are actuated resulting in a vertical flapping of thewing portions.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the claimed as new is:

invention, what is 1. A toy aeroplane comprising a fuselage mem- I her,a wing structure, said wing structure including a central section andflappable end sections, said central section including a reinforcingmember, a drive shaft including cranks therein, pitmans extending fromthe cranks and connectors between the pitmans and the flappablesections, said connectors consisting of a substantially triangu arshaped wire member having one portion rotatably mounted on thecorresponding end of the reinforcing member, said triangular shapedmember being divided at the intermediate portion of one side portion andhaving its end portions disposed laterally in substantially parallelrelation to span a portion of the corresponding fiappable section, thecorresponding pitman being connected to the outstanding apex portion ofthe triangular shaped wire member.

2. A toy aeroplane comprising a fuselage member, a wing structure, saidwingstructure including a central section and fiappable end sections,said central section including a reinforcing member, a drive. shaftincluding cranks therein, pitmans extending from the cranks andconnectors between the pitmans and the fiappable sections, saidconnectors consisting of a substantially triangular shaped wire memberhaving one portion rotatably mounted on the corresponding end of thereinforcing member, said triangular shaped member being divided at theintermediate portion of one side portion and having its end portionsdisposed laterally in substantially parallel relation to span apo'rtionof the corresponding fiappable section, the corresponding ,pitman beingconnected to the outstanding apex portion of the triangular shaped vwiremember, each of the said fiappable end sections including a reinforcingstructure, said parallel end portions of the connectors being adapted tooverlap the corresponding reinforcing structures, and tie means wrappedaround the end portions of the connectors and the reinforcing structurefor securing the connectors to the reinforcing structures of thefiappable sections.
